One of the most frequent customer questions: "How long will your glass wool insulation layer last?" United Insulation tells you directly that glass wool, installed correctly, can last over 50 years, even up to the same lifetime as the building!

1.Inorganic, thus naturally non-aging material.

Glass wool is made up of molten glass fibers and does not include any organic binders; quality products are also free from formaldehyde. It will never age, powder, or shrink throughout time, in opposition to organic insulation materials. Glass wool buildings from the 1960s and 70s in Europe and America, when they are deconstructed today and tested, present almost no change in thermal conductivity!

2.Real-life longevity data:

- Roofing/Exterior Wall Systems: 50–70 years (European Building Standards)

- Properly sealed interior partitions/floors: virtually permanent

- Exposure to Humidity and High Temperature: For instance, the roofs that do not have a waterproof vapor barrier have the potential to settle after 20–30 years.

3.Three Key Factors Affecting Lifespan:

- Waterproofing and Moisture Proofing: It needs to be used along with a breathable waterproof membrane or aluminum foil cladding in order to avoid long-term buildup of water.

- Insufficient Compaction during Construction: Density design values should not be higher than the pressure applied to avoid breakage of the fibers and settling.

- UV Protection: Glass wool that is exposed requires a protective coating to prevent it from embrittling with time.

4.What We've Done?

United Insulation exports glass wool made of high-quality centrifugal fibers and thermosetting resins. The fibers are long, tough, and durable. It has passed the EU CE durability test and provides a performance guarantee in the Middle East, Europe, and Australia.

Conclusion: As long as waterproofing measures are in place and construction is carried out in accordance with building regulations, the actual service life of glass wool far exceeds that of organic insulation materials, truly realizing "one-time insulation, lifelong peace of mind."
